If they still peck at him after you make him a chair or something to help him, separate him... maybe put one or two friends in there that don't peck him. How old are they again? Just hatched... make sure that they are warm too.
The "chair" idea is really nifty! tcooper23, is the spradle leg only impacting the lower part or the hips, too? Here is a link of a site where more of the leg was impacted and two sets of the little hobbles (could use the bandaid for this) were required. Might this help the backwards alignment?
I used a small clear plastic container to put my chick in. Kept it safe from pecking and also allowed
it to see the others andstay warm .
I had one success and one failure.but the failure had other problems as well.
Both spraddle leg (disintegration/malformation of hip socket) and curled toes are a factor from incubation temperatures being too high. Slippery surfaces after hatching will also damage a just hatched chick's joints. Spraddle leg could also be genetic. Please don't try to breed from the birds you select to keep from this hatch.
